@Zanzibarball: Once no colonial power will be left to mention. If you want to go further with this series you can mention historical superpowers like the Roman Empire (Italy, France, Greece, Egypt etc), HRE (Germany, Austria, Low Countries, Czech) and, yes, the Ottoman Empire (Turkey, Egypt, Serbia, Greece). Also intergouvernmental organizations are possible (European Union, Arab League, ASEAN).

@the admin: In my opinion, it will be good if comic series like Zanzibarball's colonial empire comics and my meeting comics are more easally retrievable, by a tag or a menu bar. Do you agree? I do understand if it's too difficult, time consuming or just unnecessary.
